Rob:

Don't know exactly what a BT-55 size is (been into the high power too long,
I guess <g>), but we offer phenolic in 29mm. Also, we offer G10 fins in
0.062, 0.093, and 0.125 thicknesses.

PML 29mm tubing fits perfectly inside BT-55.  I made, launched, and lost
a Goblin (not an upscale) on a G40 using BT-55, PML 29mm tubing, and G10
fins.

http://www.mcmaster.com has phenolic and G10 tubes and sheet. They gall it
Garolite. Tubes are in sizes up to about 2", all are fractional inch sizes. (No
minimum order, MC/Visa accepted.)

Tom,
I think ( please correct me) that Garolite is like the liners in an AreoTech
motor, not like the Phenolic ***d paper that PML sells.

Grade XX is like Aerotech liner, but it works fine for BT's also.
Grade LE is fine cotton cloth ***d with phenolic. I've used this for BT's
but although very strong, it's just as brittle.
Grade G10 is fiberglass cloth/epoxy. The best for airframes but expensive. I've
had 54mm, 1/16 wall G10 survive a core sample from 17000 ft. (Dig out the dirt,
remove the L750)

I have most sizes of G10 sheet in stock from .015" to 3/16".  I sell the .062"
in 12" x 24" sheets for $9.50 / sheet, the .093" in 12" x 36" sheets for
$18.72/sheet, and .125" in 18" x 24" sheets for $27.00 / sheet.

An interesting source of fairly small diameter phenolic tubing is those 18' long
telescoping fishing rods.   I bought 3 at local closeout for $10 for all, and the

nesting tubing is tapered - where'ya gonna find that?

Thanks,

Rick

There are several applications for nesting tapered tube -- but I think
you'll find all of it is epoxy/glass, rather than phenolic.  I'm
practically certain that fishing rod isn't phenolic -- those things have
to flex, and phenolic isn't really very good at that.

Shorter casting fishing poles are graphite, but these really long poles (most made in
China)  are not used for casting but just to kind of float fish - (they're 18 feet
long
or more fully telescoped out).  They're usually around $12-20 at most big outlet type
sporting goods stores.  They *are* painted black on the outside, but on the inside is
the orange-brown spiral tubing.   The largest section at the base is about Estes D
size.

It smells like phenolic - (I guess that's the easiest test.)

Thanks,

Rick
